Gephi API

[cklee]

"Lookup is the backbone of a NetBeans Platform application and must be cited first. We repeatedly use the service provider scenario to propose extensible features like algorithms, filters, or new file format support. I really like that a single annotation is enough to add a feature and directly see it integrated in the user interface." - dzone interview

From last year's wikispace:

Code: Select all

Generator[] generators = Lookup.getDefault().lookupAll(Generator.class).toArray(new Generator[0]);

and
http://openide.netbeans.org/lookup/

All good references, but could someone help me point out instances in the current Gephi 0.7 build in PreviewAPI? I'd rather see it used in the source.

I recommend Netbeans Platfrom's screencast about Lookup, available here.
Many tutorials about Netbeans Platfrom can be found on the website.

There is no extensive use of Lookup in the Preview modules, except for PreviewController. However that must change with the planned refactoring, as more modularity will be developed. Just an exemple applied to Preview, one can imagine Properties class implementing PreviewProperty and setting the annotation

Code: Select all

@ServiceProvider(service=PreviewProperty.class)

and the UI doing

Code: Select all

for(PreviewProperty p : Lookup.getDefault().lookupAll(PreviewProperty.class)) {
   //display property
}

for knowing about declared properties.

The power of this system is that any plug-in just create a PreviewProperty implementation and use @ServiceProvider to be integrated.
